Abstract

Provided is a fuel pipe 4 that is connected with a fuel distribution pipe 3 which distributes and supplies fuel to a plurality of fuel injection devices 2, the fuel pipe being equipped with a pipe body 41 and a connection head part 42 fastened to the fuel distribution pipe 3 by a cap nut 5, wherein the connection head part 42 has: a first curved portion 43 which is curved in a circular shape in a reference cross-section cut perpendicularly to a central axis line A of the fuel pipe 4 and which is to abut against a seat surface 36 formed on an inner peripheral surface of the fuel distribution pipe 3; a second curved portion 44 which is curved in a circular shape in the reference cross-section and which is locked on a locking surface 54 formed on an inner peripheral surface of the cap nut 5; and a straight portion 45 which extends linearly in the reference cross-section and which connects between the first curved portion 43 and the second curved portion 44.
